Public bug reported:
Transparent hugepages, which is a major performance enhancement in the
2.6.38 kernel is not enabled in the 11.04 kernel.:
$ cat /etc/issue
Ubuntu natty (development branch) \n \l
$ grep TRANSPARENT /boot/config-2.6.38-7-server
# CONFIG_TRANSPARENT_HUGEPAGE is not set
$ grep TRANSPARENT /boot/config-2.6.38-7-generic
# CONFIG_TRANSPARENT_HUGEPAGE is not set
$
If this is the way 11.04 kernels will be built, it's a bummer.
